A single-person spacecraft is a vehicle designed for space travel. [1] The concept has been used in science fiction and actual ships [1] such as the Mercury capsule, Vostok and some suborbital designs. Single-person spacecraft have been envisioned as a supplement or replacement for space suits in certain applications. The Von Braun Bottle suit ...
Bioastronautics is a specialty area of biological and astronautical research which encompasses numerous aspects of biological, behavioral, and medical concern governing humans and other living organisms in outer space; and includes the design of space vehicle payloads, space habitats, and life-support systems.
Space biology – studies to build a better understanding of how spaceflight affects living systems in spacecraft, or in ground-based experiments that mimic aspects of spaceflight [4] Space chemistry – Reactions of elements to form more complex compounds, such as amino acids, are key to the study of chemistry in space.

Nucleic acids may not be the only biomolecules in the universe capable of coding for life processes. [1]Astrobiology (also xenology or exobiology) is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events. [2]
that organic molecules originated in space (perhaps to be distributed to Earth) [14] that life originated from these molecules, extraterrestrially [8] that this extraterrestrial life was transported to Earth. [19] The creation and distribution of organic molecules from space is now uncontroversial; it is known as pseudo-panspermia. The jump ...
The sparseness of interstellar and interplanetary space results in some unusual chemistry, since symmetry-forbidden reactions cannot occur except on the longest of timescales. For this reason, molecules and molecular ions which are unstable on Earth can be highly abundant in space, for example the H 3 + ion.
The spacecraft reached the space station last weekend (NASA) While space is an airless vacuum , it is full of molecules that have odors when humans smell them in safe conditions.
Most spacecraft have some variety of rocket engine, and thus most research efforts focus on some variety of rocket propulsion, such as chemical, nuclear or electric. Spacecraft design – a specialized form of systems engineering that centers on combining all the necessary subsystems for a particular launch vehicle or satellite .
